=head1 EXPORT

The following subroutines are exported on demand.

    use Test::Net::LDAP::Util qw(
        ldap_result_ok
        ldap_result_is
        ldap_mockify
        ldap_dn_is
    );

All the subroutines are exported if C<:all> is specified.

    use Test::Net::LDAP::Util ':all';

=head2 ldap_result_ok

    ldap_result_ok($mesg, $name);

Tests the result of an LDAP operation to see if the code is C.

C<$mesg> is either a Net::LDAP::Message object returned by LDAP operation
methods or a result code.

C<$name> is the optional test name.

=cut

sub ldap_result_ok {
    my ($mesg, $name) = @_;

    return ldap_result_is($mesg, LDAP_SUCCESS, $name);
}

=head2 ldap_result_is

    ldap_result_is($mesg, $expect, $name);

Tests the result of an LDAP operation to see if the code is equal to C<$expect>.

The values of C<$mesg> and C<$expect> are either a Net::LDAP::Message object
returned by LDAP operation methods or a result code.

C<$name> is the optional test name.

=head2 ldap_mockify

    ldap_mockify {
        # CODE
    };

Inside the code block, all the occurrences of C are replaced by
C.
See L for more details.

=cut

=head2 ldap_dn_is

    ldap_dn_is($actual_dn, $expect_dn, $name);

Tests equality of two DNs that are not necessarily canonicalized.

The comparison is case-insensitive.
